Erratum to: Measurement of light-by-light scattering and search for axion-like particles with 2.2 nb−1 of Pb+Pb data with the ATLAS detector

G. Aad, B. Abbott, D. C. Abbott, A. Abed Abud et autres

One correction is noted for the paper, which does not affect the results reported. The rightpanel of figure 9 is corrected as it contained the “internal” label, giving the misleadingimpression on the credibility of the figure.
